The World
Record for the Earliest Snake

Snakes evolved from
lizard-like ancestors and are believed to have appeared for the first
time during the early Cretaceous period, perhaps 120 million years ago.
The oldest snake fossils were found in Algeria, in deposits about 100
million years old, although they consist of little more than a few damaged
vertebrae. The oldest complete snake fossil, found in the Middle East
in deposits about 94-96 million years old, measured about 1m (3ft 4in)
long and belonged to a species called Paryachis problematicus;
however, some experts still question whether this was a very elongated
lizard (it had minimal back legs) or a primitive snake.
